Get the platform-specific configuration JSON needed to install a single skill. Returns a JSON object with config_path (where to write the config), config (the JSON to write), and instructions (human-readable setup steps). This tool is read-only and does NOT write any files.

loaditout-mcp-server Write Risk 2/5

AI agents use install_skill to create or modify resources in Loaditout. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

Without a policy, an AI agent could call install_skill repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Loaditout.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the install_skill tool do? +

Get the platform-specific configuration JSON needed to install a single skill. Returns a JSON object with config_path (where to write the config), config (the JSON to write), and instructions (human-readable setup steps). This tool is read-only and does NOT write any files. Use this when the user wants to install a specific skill and you need the exact config for their agent platform. Do not use this for batch installs (use install_batch instead) or for packs (use install_pack instead). The skill slug is automatically saved to agent memory after calling this tool.. It is categorised as a Write tool in the Loaditout MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on install_skill? +

Add a rule in your Intercept YAML policy under the tools section for install_skill. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Loaditout MCP server.

What risk level is install_skill? +

install_skill is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit install_skill? +

Yes. Add a rate_limit block to the install_skill rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block install_skill completely? +

Set action: deny in the Intercept policy for install_skill. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides install_skill? +

install_skill is provided by the Loaditout MCP server (loaditout-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
